How to set the values of Global variables from Delphi code.

rbuser

Im using Delphi 6 RB 7.

I have a couple of Global Variable in my report and its value need to be
changed before the Report is printed. How can I do this ?

Gloabl Variables in ppReport1 :

var
AAA: String;


In my delphi code I need to do this

ppReport1.AAA := ' This is a Test ';
ppReport1.Print;


Thanks in advance

Hi Thatchi,

You will need to use the Report Parameters feature to assign your global
variables in RAP a value. Take a look a the following example of how to use
parameters to assign values in RAP.

Hi Nico !
Thanks, but does RB 7.0 support parameters ? I thought it did not, thats why
I wanted to use Global variables. Any way I got that running by using one of
the sample code what u gave in one of the earlier posts.

lGlobalCreateProgram.SourceLines.Clear;
lGlobalCreateProgram.SourceLines.Add('procedure GlobalOnCreate; ');
lGlobalCreateProgram.SourceLines.Add('begin' + #13#10);

etc. This works fine, but for some reason I had to use these two units to
get it running.

raTypes, raClass

Why is that ?

Another question, will report be slowed down when RAP and Global var are
used ?


Thanks .

Hi Thatchi,



Yes, sorry, I missed that you were using RB 7.



The raTypes and raClass files are probably needed for some of the objects
and types you are using in your code.

Question: Do you incur any performance penalty by using the RAP interpreter?



Answer: The penalties are negligible. This is due to the fact that RAP is
what we call a hybrid interpreter. While it is, in fact, an interpreter, it
is actually working as a pass-through to compiled code. Thus, when the
interpreter encounters an Object Pascal command in the RAP code, it passes
it through to the compiled code which handles this command. The result is
that your reports using RAP will execute with comparable performance to
those that have event handlers coded in Delphi.
